Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475566, here are decompositions:

107 + 31475459 = 31475566
113 + 31475453 = 31475566
137 + 31475429 = 31475566
173 + 31475393 = 31475566
179 + 31475387 = 31475566
467 + 31475099 = 31475566
557 + 31475009 = 31475566
569 + 31474997 = 31475566

Showing the first eight; more decompositions exist.
